Ingredients You’ll Need

2 tbsp. extra-virgin olive oil: A quality olive oil enhances the flavor of the entire dish.
2 oil-packed anchovy fillets: These provide a savory umami boost. If you’re not a fan, you can skip them or replace them with capers for a similar depth.
1/2 cup panko breadcrumbs: They add a delightful crunch. You could use regular breadcrumbs, but panko is lighter and crispier.
1 1/2 tsp. lemon zest (from 1 lemon): This brightens the dish, making it more vibrant. Fresh is best for maximum flavor.
1 lb. rigatoni (or pasta of choice): Rigatoni holds sauce beautifully but feel free to swap for your preferred pasta.
2 tbsp. extra-virgin olive oil: Another splash for sautéing the veggies adds more flavor to the dish.
2 tbsp. butter: Butter adds richness and depth. You can substitute with more olive oil for a vegan option.
2 large leeks: These are the star of the dish. Make sure to clean them well to remove any dirt or grit.
4 garlic cloves: Fresh garlic adds warmth and depth. Always slice them thin for a perfect sauté.
4 packed cups fresh baby spinach: Spinach not only enhances nutrition but also adds a beautiful green color.
1 cup frozen green peas: No need to thaw them; they’re a perfect fresh addition when tossed in at the end.
1 1/4 tsp. kosher salt: Adjust based on your taste. Use less if you’re watching your sodium.
1/2 tsp. black pepper: Freshly ground gives the best flavor.
1/3 cup (packed) fresh basil leaves: Offers a fragrant, fresh note that’s essential for the sauce.
2 tbsp. fresh lemon juice (from 1 lemon): Provides acidity to balance the richness of the sauce.
1/2 cup grated parmesan plus more for garnishing: Parmesan ties all the elements together. You can substitute with a vegetarian-friendly cheese if needed.

How to Make Caramelized Leek Pasta

Prep the Leeks: Bring a large pot of generously salted water to a boil. Place your sliced leeks in a bowl of water to clean them thoroughly. Drain and pat them dry before setting aside—this little bath is crucial since leeks can trap dirt between their layers.
Prepare the Anchovy Breadcrumbs: In a large skillet over medium-low heat, heat 2 tablespoons of olive oil. Add the anchovy fillets, mashing and stirring until they dissolve in the oil. Mix in 1/2 cup panko breadcrumbs and cook for about 4 to 5 minutes, stirring, until golden and crisp. Remove from heat and stir in 1 1/2 teaspoons lemon zest. Transfer to a bowl and set aside; wipe the skillet clean for later use.
Boil the Pasta: By now, your water should be boiling. Add 1 lb. rigatoni (or pasta of choice) and cook according to package directions until al dente. Before draining, reserve about 2 cups of the pasta cooking water. Drain the pasta and return it to the pot while you sauté the vegetables.
Sauté the Vegetables: In the same skillet used for the breadcrumbs, add 2 tablespoons of olive oil and 2 tablespoons of butter over medium heat. Toss in the cleaned leeks, cooking for about 7 to 8 minutes until they soften. Stir in 4 sliced garlic cloves and cook for just one more minute until fragrant. Next, add 4 packed cups of fresh baby spinach, cooking until wilted—this should take about 2 minutes. Finally, stir in 1 cup frozen green peas and cook for another 1 to 2 minutes until heated through. Season with 1 1/4 teaspoons kosher salt and 1/2 teaspoon black pepper.
Blend the Sauce: Transfer the sautéed vegetable mixture to a blender. Add the fresh basil leaves and 2 tablespoons of fresh lemon juice. Pour in 1 cup of the reserved pasta cooking water and blend until smooth and creamy. This will form a beautiful green sauce that serves as the heart of your pasta dish.
Combine Sauce with Pasta: Return the blended sauce either to the skillet or straight to the pot with the drained pasta. Set the heat to medium and gradually add the remaining 1 cup of reserved pasta cooking water along with 1/2 cup grated parmesan. Toss until the pasta is beautifully coated in the green sauce, and the texture is creamy. Taste, and feel free to adjust with more salt, pepper, or parmesan as desired.
Serve: Scoop the pasta into bowls, generously sprinkling the anchovy breadcrumbs atop. Finish with a sprinkle of extra grated parmesan, a touch of cracked black pepper, and a drizzle of olive oil for a polished touch.

Storing & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. You can also freeze the pasta for up to 3 months—just make sure to place it in a freezer-safe container. To reheat, simply warm in a saucepan over medium heat, stirring and adding a splash of water if needed to revive the sauce. Keep in mind that texture may change slightly upon reheating, but a little stirring and water will help bring it back to life.

Chef’s Helpful Tips

Clean your leeks thoroughly to avoid gritty bites; slicing and soaking helps immensely.
For an even creamier sauce, you can blend in a splash of heavy cream or some cream cheese.
If your pasta sauce feels too thick, gradually stir in more of the reserved pasta cooking water to achieve your desired consistency.
To add a little more depth, try finishing your pasta with a sprinkle of smoked paprika or chili flakes for a kick.
This recipe is make-ahead friendly, so feel free to prepare the sauce a day in advance and just cook the pasta and combine when you’re ready to serve.

Recipe FAQs

Can I use other types of pasta?

Absolutely! While rigatoni is great for holding onto the sauce, you can use any pasta shape you prefer, such as penne, fusilli, or even spaghetti. Just adjust the cooking time based on the type of pasta you choose.

Are there any substitutes for leeks?

If leeks aren’t available, you can use shallots or sweet onions as a great alternative. They’ll provide a similar sweetness and depth to the dish, though the flavor will vary slightly.

Can I make this dish vegetarian?

Yes! Simply omit the anchovy fillets and instead add some sautéed mushrooms or more vegetables. You might also want to swap in a vegetarian cheese for the parmesan to make it fully vegetarian-friendly.

How do I store leftovers properly?

Store any leftover pasta in an airtight container in the fridge for up to 3 days. Make sure it’s completely cooled before sealing. If you want to freeze it, use a freezer-safe container and try to consume it within 3 months for the best taste!
